Background color when using RibbonWindow

It seems that when I use a RibbonWindow instead of Window for my root element the background of the window is turned Black. Remove the RibbonWindow and it reverts back to the System Windows color. Is this by design?

FYI, I an using a DockPanel as the layout panel in my window and the Ribbon is docked to the top.

I believe this is due to some of the interop code which we used to allow the RibbonWindow to integrate with the title bar. A super easy workaround is to just set the Background on the Window to White and it should look as expected.

to implement a Ribbon so they're trying to prioritize that request and see how it fits in their schedule. @zappoo, a new Ribbon was promised a while ago but due to competing priorities (.NET 4, VS2010), Ribbon did not get much attention. We've been working
on a new release and also our licensing approach. We will have an update towards the end of July 2010. @dgennetten, we will have an update towards the end of July 2010. But please note that the new release will be based on .NET 3.5 and not .NET 4. Having said
that, one of our scenarios is to ensure that it can work with WPF4 applications as well. -Saied SaiedKhanahmadi Jun 17 at 5:16 PM
